Eaton DCG3104FXM DC Disconnect - NEMA 4X 1000V
Part Number: DCG3104FXM
Quick Summary
Eaton DCG3104FXM heavy duty DC disconnect provides safe isolation for solar PV systems. Engineers often struggle with corrosion, outdoor exposure, and tight installation footprints across industrial sites. Certified to NEC 690 via UL 1741 and UL 98B, with a NEMA 4X enclosure in 316 stainless steel for outdoor reliability. Its 1000 VDC system voltage and 200 A per circuit rating enable scalable PV designs while maintaining grounded, fusible protection. This combination reduces downtime, simplifies compliance, and lowers total cost of ownership in demanding environments. Additionally, compatibility with large main lugs and isolated return paths helps installers meet field requirements quickly.
